iro stares WALL CONSTRUCTION.

Application filed December "lbis invention relates to wall construction, and more especially to vvalls for furnaces and the like, subjected to high degrees of heat, and my object is to produce a Wall from which at relatively small eX- pense and in ashort time, a burned section can be removed and replaced by a new section Without affecting the strength or solidity ot the unburned section. Another object is to produce a Wall construction in which provision is made for expansion vertically and longitudinally'.

-With these general vobjects in View the invention consists in certain novel and useful features of construction and organiza-l tion of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the acconipanying drawings, in which Figure l is a fragmental perspective of a double -Wall embodyingl the invention.

substitute for a pair of removable tiles as shown in Figure 7. l Q

ln the said drawings, a. Wall structure is shown composed of an inner member l and an outer member 2 generally spaced apart longitudinally at 3 but interlocked together `at predetermined levels Without interfering with expansion or contraction.

The outer member, as not subjected toy contact with flame, is erected of suitably arranged ordinary brick' 4 or the like, and at suitably' spaced levels there are single courses of the brick and tiles 5, which latter are provided at their inner ends with laterilly-projecting rounded lugs or ears 6. Preferably the distance between adjacent tiles 5, of the same course, equals the length of two bricks.

The inner member is erected ot suitably arranged refractory brick or the like 7, and pairs of tiles 8, placed at the saine levels as tiles 5, and the pairs of tiles S, project outward into the outer member and substan tially iill the spaces between` adjacent tiles for the width ot the inner vertical course ot the brick 4, each tile S having a recess 9 in its outer side edge loosely receiving lthe proximate lug or ear 6 of the adjacent tile 5, the interlocking arrangement of the ears and recesses being sucb that indepelldent endwise movement iinwardly or outwardly of either the tiles 5 or the tiles 8 is prevented. .Tiles 8 engaging the same tile 5, are separated by pairs of interposed bricks 7 of the inner member, and suchbricks in thev same course as the said tiles 8, hold the latter in side'vvise" abutting relation at the inner face of the inner member of the Wall, but from the plane of such face the adjacent side edges of the pairs of tiles diverge outward relatively to provide interposed V shaped spaces 10,.tl1 e parts being so proportioned that it is possible, when a pairot bricks in a particular course are removed, to pivotally ,swing either adjacent tile 8 around the engaging lug or ear 6 to 4permit the tile to be Withdrawniwithout interference from the companion tile 8, as shown by Figure 7. The removedtile or tiles can be replaced or new one' substituted by a reversal of the mai nipulation described, and the method of operation. described can be followed at any intermediate point and level on the inner face all the i different levels,

of the wall, as ,all quired is the chiseling out of such pair ot bricks between thetwo tiles where the removal is to be effected. it being understood of course, that the burned .or imperfect brick 7 in the vicinity ot the tile or tiles to be removed, will also be replaced Vwhen the replacement of the tiles occurs. As an illustration, if it be assumed that thewall needs repair within the ellipse traced on Figure l, brick 7 and the two tiles touched by or within the elliptical figure, may be readily removed. the brick in any desired man"- ner and the tile as explained, and a repair made Without ,affecting the remainder ot the inner members of the wall or the outer member spaced from but in interlocking relation therewith. j

The 'tiies 5 end 8. and the Ybricks of the inner and outer walls inward of tiles 5 and outward of`tiles 8 respectively` are slightly spaced apart for facilitation of vertical and longitudinal expansion of the inner wall member. Tt has been found that ot' the 1ongitudinal expansion of such member compara-ti :ly irfne occurs at the for this reason it is feasible to abut the tiles 8 sidewise at their inner extremities and against the interposed'l pairs of bricky 7. To accommodate variable vertical expansion at a course of cover tiles ll for each course ot interlocking tiles, is provided. The cover tiles' are preferably of such width that every fourth one overlies the out` er ends of a pair of adjacent tiles8, the two intermediate cover tiles vvjointly overlying one of the tiles 5 and the biiclr`i\'oik 4 flanking/such tile. i The cover tiles, like the tiles 5, are permanent, being cemented or otherwise secured to and as a part of the outer wall member. They may be of step form (see Figure 4) to provide spaces between them and the overlapped tiles 8, but tliecheaper and fore preferred method of providing foi-,the spacing of the inner oi overlapping ends of the covertile `tronr the tile 8 is to provide deep Icourses of mortar or cement l2 for the cover tiles, as by so doing the spaces can be provided by using cnvrntional or stock rile ot uniform thickness soii'iewhat less than v l .posed pairs spaced apart'by'the outer Wall bricks, it being also pretei'rei that thecover tiles shall project across the space 3 to subdivide the same as to depth, into as man),` divisions as there'are courses oi' cover tile. This subdivision of the space 3 is desirable, when twohigh walls 1y and 2 are provided in proximity to each other,

`that olthe it is desirable to till the space with crushed tire brick or the like, and it subdivided as explained, the {illing will not pack materially and hence will;not expand laterally enough yto warp'the wall members, as might occur it the lilling was a solid mass' from the bottom to the top of the wall. To facilipreliminary work reinner tace, and

tate longitudinal expansion of the inner wall in the brick courses between the courses conlength of a brick apart as contrasted with the same tilesin the preceding figures` where they are'two' bricks lengths apart., This difference is immaterial in'principle and is made onlyvto avoid the necessity of making the tiles l4 oi undesirable width and weight.

It wil 4also be noted that the tiles 14 are permanent tiles in the sense that they'cannot be removed by pivotal adjustmeutshould adjacent bricks 7 be chiselcd out oi'otherwise removed. It is anticipated that certain parts of the inner wall,-the upper for example-will never be subjected vto such continuous contact with iame as to be in needof replacement, and at such points it may be desirable to employ tiles of the character or type disclosed by Figures 8 and 9, as with such tiles.longituc liiial and vertical expansion can be accommodated as conveniently as where the removable tiles 8 are employed. 'j

From the above description it will be apparent that I have ,produced a wall einbfidyl ing the features of construction and larrangement set forth as desirable, and it is to be understood that I reserve the right to make such changes as properly tall within the spirit and scope ot the appended claims.
